Great theories led by great thinkers have great controversies--the fledgling evolution theory was in fact, heavily influenced by the hypotheses made by Jean Baptist Lamarck, a prominent French naturalist who is famous for his fallacious yet stunningly ingenious 'use and disuse theory.' Lamarck was one of the leading thinkers of his era who first recognized that living things have changed over time and furthermore have adapted to their environments. Setting aside the disproved hypotheses, the significance Lamarck has in the history of evolution theory is simply immense. Here are some hypotheses made by Lamarck
1. Tendency towards perfection
Lamarck believed that all organim proceed towards perfection and complexity. As a result, the organism are consistently change and acquire traits that make them fit better to the environment. In Lamark's view, for instance, the complex wings of the birds are byproducts of its ancestor's urge to fly.
2.Use and disuse
The tendency towards perfection eventually caused organisms to alter or develop new ways of using their organs. Lamarck proposed that the selective use or disuse of an organ led to a change in that organ that was then passed on to offspring.
3. Inheritance of acquired traits
Lamarck believed that acquired traits can be inherited. In a nutshell, if you grow huge abs, your children would inherit big muscles as well.
